[Lu...] Posted Thursday at 09:16 PM Share Posted Thursday at 09:16 PM Hello, I am having difficulty with some runout results that don't make sense to me. The position and form in the feature menu look good to me (only about .0006 different than the datum) and yet in the characteristic for the runout, it is showing about .040 which is very far out of tolerance. The form on the datum is only .0008 and the form on the feature is only .0003 and the position looks good, yet i can not seem to get a good runout result. Sometimes changing the amount of points changes the result but I haven't found a consistent number. Any advice would be appreciated. Link to comment Share on other sites More sharing options...

[Da...] Posted Friday at 04:29 AM Share Posted Friday at 04:29 AM (edited) First of all, be aware that when you use a cylinder in a run-out, it will always be a total run-out over the whole length of the cylinder. Not what you might want. Secondly, the actuals do look gruesome. Yeah, position and form might be okay, but the angles are huge.

[Ri...] Posted Friday at 11:34 AM Share Posted Friday at 11:34 AM Look at the depth of the cylinder (.150), now look at the A2 value, .0957°. Do the same for Datum F. This is a typical situation with short 3D features where the A1 and or A2 values are most likely errant. Also look at the distance from one to the other, you can calculate the error. A simple layout would show you if it's true or not for 28-Cylinder. Adjust your constraints accordingly with layout results. Link to comment Share on other sites More sharing options...
